Finally got around to doing the finishing touches on this box and getting some pictures up. I've built a copy of Fochps sub box here. I carry a lot of packages / boxes in my truck and wanted something that would sound great, fit a 12", while not drastically taking up a lot of cargo room. I also wanted it to blend in for a clean factory look.
Huge props to the OP for the great design and help. Having the box wrap around the wheel well is what really minimizes the cargo loss and I'm sure it wasn't an easy to design to come up with!

He sent me bunch of pictures of the box as well as the dimensions. I stumbled on a page explaining how to mock up designs in google sketchup:
Ported Box Design: A Tutorial *Updated 6/30* - Subwoofers / Enclosures - SMD Forum
Over a couple good hours of messing around, I was able to recreate the design:
This allowed me to figure out the exact board sizes I was going to cut:
Face: 2'5" x 19"
Backboard: 2'5" x 19" ( complex cut printout )
Top Board: 2'5" x 12.5"
Rear Board: 9.5" x 12.5"
Shelf Board: 12" (+longer if needed) x 12.5"
Diagonal Board: 9 13/16" x 12.5"
Bottom Board: 11.5" x 12.5"
Front Board: 1' 4 1/8" x 12.5"
Port Board: 1' 8 3/4" x 12.5"
Suwoofer opening is 7 5/8" from outside right
7 3/4" from bottom
(all 3/4" mdf)
I then built it using pointers from this site:

I painted it a primer grey to start with, but wasn't able to find a shade dark enough for my taste so I broke down and ordered some carpet for it. While waiting for the carpet arrive I spent some time and bolted the box down. It's a bit overkill, but I didn't want a ~80lb box flying up to meet me in the event of a collision. Also, the box is so securely attached now I can't help, but think it might add some small amount of additional ouput to the setup; all of the woofer movement will be air displacement instead of possibly vibrating the enclosure around a bit.
Here's what I came up with:
Yes, those are sockets being used as spacers. Don't laugh... :shocked:
There is also a third small bracket going into the wheel well not pictured here.

For the carpeting, I ordered a bunch of samples from
Auto Carpet for Car, Truck, Van - Stock Interiors and ended up going with Plush Cut Pile 8655 / Sandstone. It's almost a perfect match for the oak interior. I ordered one minimum order of carpet by the yard for it:
Toyota 4Runner Carpet By The Yard
Had to sand down a lot of the 8 coats of grey primer from the previous painting, but the carpeting went well. Attached it with 3M Spray Adhesive.

And here is the final product:

Ended up installing a RF P3D4-12 Punch wired down to 2ohms and a RF R500-1D Prime Amplifier. I was a bit hesitant to install it under the rear passenger seat at first, but after running it pretty hard for over an hour with the carpet and seat folded down on it- it barely is warm to the touch.

Put the remote bass knob on the side of the console along with the head unit remote. This lets me adjust anything on the radio / amp from where my hand naturally rests after shifting. Pretty cool.
The box really hits clean and loud. Thanks again for the help from Fochps!
If anyone is looking for a great 12" ported design for their 4runner, I can't recommend this one enough. :thumb3:
